Frankliniella tritici

Definition

A minute, flower-dwelling thrips species in the family Thripidae, commonly known as the eastern flower thrips. Adults possess strap-like wings fringed with long setae—an aerodynamic adaptation that reduces drag and energy expenditure during flight in very small insects. The species feeds by rupturing individual plant cells to extract contents and is a documented vector of tospoviruses (Bunyavirales), causing economically significant damage to small fruits (strawberries, grapes, blueberries, blackberries) and field crops (alfalfa, oats, beans, asparagus) in North America.

Etymology

From Frankliniella (honoring entomologist H.H. Franklin) + tritici (Latin, 'of wheat', from the original host association).

Example

In strawberry production, F. tritici populations in blossoms can transmit Tomato spotted wilt virus, requiring integrated management with selective insecticides and resistant cultivars.

Synonyms

• eastern flower thrips

Related Terms

• Thysanoptera
• Thripidae
• tospovirus
• fringed wing
• Thrips tabaci
• Frankliniella occidentalis
• western flower thrips
• Flower thrips

Usage Notes

Often confused with the more polyphagous and invasive Frankliniella occidentalis (western flower thrips); accurate identification requires slide-mounted specimens and examination of antennal segments and comb setae on abdominal tergites. The subspecies F. t. moultoni and F. t. maculata have been described but are not universally recognized.
